Abstract

An attachable and detachable wheelchair tray with an adjustable work surface is disclosed. The adjustable work surface has two parts connected with a hinge. Part one is a horizontal stationary supporting base and part two is a movable top portion which can be tilted in an angular range of from 90 degrees to 180 degrees in relationship to the horizontal base. There is also an extendible auxiliary supporting rack attached to the movable top portion that allows the user to enlarge or reduce the work surface, thus permitting access to more items, references publications at a time. All adjustments of the work surface are easily controlled with levers, buttons or foot pedals, called "Ergo Aids" which are located on or in close proximity to the wheelchair tray, in a place that is most convenient for the seated user. Fluid piston cylinders using compressed air, carbon dioxide or nitrogen provide the power required to move and adjust the tray with minimal force being applied to each control adj
